I think it's all in the invisible working-out of the bolus calculator. At the pump workshop I did recently the rep was talking about 'onset time' and 'meal rise' and 'snack size' and the bearing they have on the back-end in its calculations for any correction doses between one and four hours after bolusing (eg it allows for the expectation of a 'meal rise' of 2.8mmol/l so any corrections (in my case) within this time frame are made to a target of 8.8mmol/l rather than my standard correction target of 6mmol/l.(Edited to say there is a taper on this calculation so it's a curve on a graph rather than a fixed 2.8 figure for the whole time period - so after 2hrs it's 2.8 greater than my target, but after 4hrs it's tapered to nothing, meaning that your target aimed for by the calculator is for me to be 6 after 4hrs, and the calculator does this).Because it's all worked out for me, as I'm using the handset for testing and for bolus calculating, I don't need to know myself what my active insulin is (including bolus insulin, I mean) in terms of doing any working out myself.However, I do see the potential merit of having an actual figure in the display for active insulin, especially if I were using other means of testing or wanting to do my own calculations rather than relying on the bolus calculator (not blindly, but in an educated fashion - ie I know all my ratios and how to carb count and work out how much reduces me by how much - it's just that the calculator really, really seems to work for me without many nasty surprises!).Brain hurts.....!<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" /></blockquote>
